Get a head start on every new to-do

A new task was just added to my Todoist. Read the task and its description. If it's something only I can do, like a call or an errand, stop and do nothing. Otherwise, give me a head start: find the links, options, or information the task needs, and break it into the first [3] concrete steps. For a purchase, compare [2 to 3] options with prices; for a booking, list available times; for research, summarize what you found with sources. Add it all as a comment on the task. Don't complete, reschedule, or change the task itself. Tell me what the task was and what you added.
